I am in the process of building a carpeted plywood cover for the tub on my 2013 JKU. I have seen a lot of build threads for these and most people cut and mount a piece of plywood behind the rear seats so that if your doors are off someone can't just fold down the rear seats to gain access to your cargo. What I would prefer to do is devise a way to lock the release mechanism that allows the seats to fold down. This seems nicer in the event that I want to haul something long. Anyone out there with any good ideas?
